also I'm surprised there isn't a mention over central IL to NW IND for a secondary area

 

 

MESOSCALE DISCUSSION 0207  
NWS STORM PREDICTION CENTER NORMAN OK  
1054 AM CDT THU MAR 14 2019  
  
AREAS AFFECTED...CENTRAL AND NORTHEAST IL...NORTHWEST IN  
  
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE   
  
VALID 141554Z - 141730Z  
  
PROBABILITY OF WATCH ISSUANCE...60 PERCENT  
  
SUMMARY...THUNDERSTORMS WILL CONTINUE TO INTENSIFY OVER THE NEXT 1-2  
HOURS AND LIKELY BECOME SURFACE-BASED ACROSS CENTRAL IL.  A TORNADO  
RISK WILL PROBABLY ACCOMPANY THE STRONGER STORMS WITH THE TORNADO  
RISK PERHAPS MOVING INTO NORTHEAST IL EARLY THIS AFTERNOON.  
  
DISCUSSION...VISIBLE SATELLITE IMAGERY SHOWS MOSTLY CLEAR SKIES  
ACROSS CENTRAL IL WITH BREAKS IN THE CLOUDS OVER NORTHEAST IL INTO  
NORTHWEST IN AS OF 1030AM CDT.  A MID-LEVEL VORTICITY MAXIMUM  
LOCATED OVER THE MID MS VALLEY IS EXPECTED TO MOVE NORTHEAST ACROSS  
CENTRAL IL DURING THE NEXT SEVERAL HOURS.  
  
SURFACE ANALYSIS SHOWS TEMPERATURES WARMING INTO THE LOWER 60S WITH  
DEWPOINTS RISING INTO THE UPPER 50S OVER CENTRAL IL.  THE 12Z  
LINCOLN, IL RAOB SHOWED A VERY COLD 500MB TEMPERATURE (-21.7 DEG C)  
WITH AN 8 DEGREE C/KM 700-500MB LAPSE RATE, IT APPEARS 750-1000 J/KG  
MLCAPE IS POSSIBLE.  GIVEN THE VERY STRONG TO EXTREME SHEAR PROFILE  
COUPLED WITH THE VERY STEEP LAPSE RATE, IT APPEARS TORNADO POTENTIAL  
IS GREATER THAN PREVIOUSLY ANTICIPATED AND AN UPGRADE IN TORNADO  
PROBABILITIES WILL BE REFLECTED IN THE UPCOMING 1630Z CONVECTIVE  
OUTLOOK.  IF ROBUST SURFACE-BASED SUPERCELLS IN FACT DEVELOP, A  
STRONG TORNADO IS POSSIBLE MAINLY EAST OF THE US51/I-39 CORRIDOR IN  
EAST-CENTRAL AND INTO NORTHEAST PORTIONS OF IL THIS AFTERNOON.

Eagerly anticipating the 1630Z SPC convective outlook.  Some changes are bound to be made, especially for central and NE IL, plus NW IN, given the storms in that area.

Not to mention that clearing along the Ohio River is bound to introduce some issues down the line for Louisville and Cincinnati as well.

Latest HRRR is handling the clearing well. Oddly, it doesnt destabilize much though. ~500 cape. Obviously enough for today, but I would have thought clearing would push to 750+

Yep, I'd say an upgrade to MDT is warranted along the OH River Valley; probably a slight deeper west into Chicago as well. Hi-res guidance is killing off those cells in western KY, which doesn't make a lot of sense given the clearing, moisture advection, wind fields, etc.

DAY 1 CONVECTIVE OUTLOOK    
NWS STORM PREDICTION CENTER NORMAN OK  
1126 AM CDT THU MAR 14 2019  
  
VALID 141630Z - 151200Z  
  
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON  
FOR NORTHEASTERN IL AND VICINITY...AND THROUGH LATE EVENING FOR  
PARTS OF THE TN AND OH VALLEYS...  
   
..SUMMARY  
  
SEVERE THUNDERSTORMS ARE LIKELY FROM PORTIONS OF THE SOUTHEAST U.S.  
INTO THE OHIO VALLEY AND SOUTHERN GREAT LAKES.  SEVERAL TORNADOES, A  
FEW OF WHICH COULD BE STRONG, DAMAGING WINDS AND ISOLATED LARGE HAIL  
WILL BE POSSIBLE THROUGH THIS EVENING.  
   
..TN VALLEY TO THE OH VALLEY THROUGH THIS EVENING  
  
A DEEP SURFACE CYCLONE IN SOUTHEASTERN NE WILL MOVE NORTHEASTWARD  
OVER IA/WI/UPPER MI BY THIS EVENING, AS AN ASSOCIATED MID-UPPER JET  
STREAK EJECTS NORTHEASTWARD FROM MO TOWARD THE LOWER GREAT LAKES.  A  
SURFACE COLD FRONT WILL PROGRESS EASTWARD FROM THE MID MS VALLEY TO  
THE OH VALLEY, AND SOUTHEASTWARD INTO THE LOWER MS VALLEY.  A NARROW  
CORRIDOR OF LOW-LEVEL MOISTENING AND SOME SURFACE HEATING IN CLOUD  
BREAKS IS EXPECTED IMMEDIATELY AHEAD OF THE COLD FRONT THROUGH THIS  
AFTERNOON, WHICH WILL SUPPORT SOME DESTABILIZATION AS FAR NORTHEAST  
SOUTHERN LOWER MI.  
  
THE STRONGEST LOW-LEVEL FLOW WILL DEVELOP NORTHEASTWARD ACROSS TN  
TOWARD OH THROUGH THE AFTERNOON.  VERTICAL SHEAR WILL BE VERY STRONG  
WITHIN THE WARM SECTOR, WITH EFFECTIVE BULK SHEAR OF 70-80 KT AND  
EFFECTIVE SRH OF 400-600 M2/S2.  BOUNDARY-LAYER DEWPOINTS IN THE LOW  
60S HAVE SPREAD AS FAR NORTH AS THE LOWER OH RIVER AS OF LATE  
MORNING, AND SOME ADDITIONAL MOISTENING IS EXPECTED TO THE NORTHEAST  
THROUGH THE AFTERNOON.  MIDLEVEL LAPSE RATES ARE NOT PARTICULARLY  
STEEP AND SURFACE HEATING WILL BE SLOWED BY THE MORNING  
CONVECTION/CLOUDS, SO MLCAPE WILL LIKELY REMAIN IN THE 500-1000 J/KG  
RANGE.  WIND PROFILES WILL CLEARLY FAVOR SUPERCELLS, AS WILL THE  
MODE OF INITIATION ALONG AND EAST OF THE FRONT (NOT STRONG LINEAR  
FORCING FOR ASCENT).  THE VERTICAL SHEAR IS ON THE HIGH END FOR THE  
MODEST BUOYANCY, BUT IT APPEARS THE COMBINATION WILL BE SUFFICIENT  
FOR THE STRONGEST/MOST SUSTAINED SUPERCELLS TO PRODUCED ISOLATED  
STRONG TORNADOES AS THE STORMS ARE ROUGHLY PACED BY THE LOW-LEVEL  
DESTABILIZATION.  
  
ADDITIONAL SUPERCELL DEVELOPMENT WILL BE POSSIBLE LATE THIS  
AFTERNOON INTO THIS EVENING ALONG THE TRAILING BOUNDARY IN THE  
VICINITY OF NORTHWESTERN AL.  THOUGH THE STRONGEST LOW-LEVEL FLOW  
WILL DEVELOP NORTH OF THIS AREA BY LATE AFTERNOON, WIND PROFILES  
WILL REMAIN FAVORABLE FOR SUPERCELLS/TORNADOES GIVEN SOME HEATING IN  
CLOUD BREAKS AND AN INCREASE IN LOW-LEVEL MOISTURE THROUGH THE  
AFTERNOON.   
   
..CENTRAL/NORTHEASTERN IL TO SOUTHERN LOWER MI THIS AFTERNOON  
  
BANDS OF CONVECTION ARE DEVELOPING ALONG THE NOSE OF THE PRIMARY  
FRONTAL SURGE/DRY SLOT NEAR AND NORTH OF SAINT LOUIS AS OF MID  
MORNING.  THE LOW LEVELS ARE DESTABILIZING NORTHWARD ACROSS IL WITH  
SURFACE HEATING IN CLOUD BREAKS AND BOUNDARY-LAYER DEWPOINTS OF  
56-60 EXPECTED TO REACH NORTHEASTERN IL BY EARLY AFTERNOON.  A  
BROKEN BAND OF LOW-TOPPED THUNDERSTORMS IS EXPECTED ALONG THE WIND  
SHIFT BY THIS AFTERNOON, WHEN STRONG VERTICAL SHEAR WILL SUPPORT  
SUPERCELLS CAPABLE OF PRODUCING TORNADOES, DAMAGING GUSTS, AND  
MARGINALLY SEVERE HAIL.  THE CONVECTION WILL SUBSEQUENTLY SPREAD  
NORTHEASTWARD TOWARD LOWER MI LATER THIS AFTERNOON.  THE DEGREE OF  
DESTABILIZATION IS MORE QUESTIONABLE COMPARED TO AREAS FARTHER  
SOUTHWEST, BUT WIND PROFILES WILL STRONGLY FAVOR ORGANIZED/SUPERCELL  
STORMS.

Ominous look on visible satellite imagery in IL.  Low level moisture still lacking a bit toward Chicago but there is still some time and we probably won't even need to get dewpoints into the 60s to have problems given the steep mid level lapse rates with partial clearing.

I’m in eastern Kankakee county. Going to head home early to keep an eye on things

instead of having 3 seperate threads might as well make this the main sever thread for the day...... so..

 

ESOSCALE DISCUSSION 0208  
NWS STORM PREDICTION CENTER NORMAN OK  
1147 AM CDT THU MAR 14 2019  
  
AREAS AFFECTED...NORTHEAST MISSISSIPPI...NORTHWEST ALABAMA...AND  
SOUTHERN TENNESSEE  
  
CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY   
  
VALID 141647Z - 141815Z  
  
PROBABILITY OF WATCH ISSUANCE...80 PERCENT  
  
SUMMARY...A GRADUAL INCREASE IN STORMS IS EXPECTED THROUGH THE  
AFTERNOON. A TORNADO WATCH WILL LIKELY BE NEEDED SOON.  
  
DISCUSSION...16Z SURFACE ANALYSIS SHOWS MUCH OF NORTHEAST  
MISSISSIPPI AND NORTHWEST ALABAMA HAS WARMED 4 TO 5 F IN THE LAST  
HOUR DESPITE SOME CLOUD COVER ACROSS THE AREA. THIS HAS LED TO AN  
INCREASE IN LOW-LEVEL INSTABILITY TO AROUND 750 TO 1000 J/KG OF  
MLCAPE. WARMING IS EXPECTED TO CONTINUE WITH LOW-LEVEL MOISTURE  
ADVECTION WHICH WILL LEAD TO MODERATE INSTABILITY BY MID-AFTERNOON.  
THE RECENT HEATING IN THIS AREA HAS PROVIDED ENOUGH INSTABILITY FOR  
A REINVIGORATION OF LIGHTNING FROM SOME OF THE CONVECTION IN  
NORTHERN MISSISSIPPI. THEREFORE, EXPECT MORE WIDESPREAD STORM  
COVERAGE WITHIN THE NEXT HOUR OR TWO AS SURFACE DESTABILIZATION  
CONTINUES TO INCREASE.   
  
DEEP-LAYER SHEAR IN THIS AREA IS VERY FAVORABLE FOR SUPERCELL AND  
LOW-LEVEL MESOCYCLONE DEVELOPMENT WITH DEEP LAYER EFFECTIVE SHEAR  
AROUND 55 TO 60 KNOTS AND 0-1 SRH AROUND 350 M2/S2 PER GWX VWP.  
THEREFORE, THESE STORMS WILL POSE A TORNADO THREAT WITH THE  
POTENTIAL FOR STRONG TORNADOES, ESPECIALLY AS SUPERCELLS MATURE INTO  
NORTHWEST ALABAMA.
